This study introduces an attempt to apply the roles of NGOs for Education for Sustainable Development (ESD) by connecting Japan and Malaysia through rainforest reforestation by community participation conducted by the Japan Malaysia Association (JMA). The JMA employs natives to plant and maintain the forest, and has devoted a research field to ecology at UNIMAS University since 1995. During this time, they began to connect these activities and ESD for school students from Japan and Malaysia. In the activity, the JMA plays important role as a hub of activity in connecting schools, the university, and natives of Japan and Malaysia as well as conserving the environment. In addition, some Japanese companies cooperate with the JMA in corporate social responsibility (CSR) activities that indirectly support environmental conservation and students’ education, thereby increasing the company’s value.
